Rev. Lett.International audienceThe first observation of the decays Λ0b→χc1pK− and Λ0b→χc2pK− is reported using a data sample corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. The following ratios of branching fractions are measuredB(Λ0b→χc1pK−)B(Λ0b→J/ψpK−)=0.242±0.014±0.013±0.009,B(Λ0b→χc2pK−)B(Λ0b→J/ψpK−)=0.248±0.020±0.014±0.009,B(Λ0b→χc2pK−)B(Λ0b→χc1pK−)=1.02±0.10±0.02±0.05,where ...
